DISPLAY-RACK.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed March 19 1906. Serial 1-10. 306,857.

To all whom it may concern:

, Be it known that I, VVILLIAM B. LOEWEN- BERG, a citizen of the United States, residing at Wabash, in the county of Wabash and State of Indiana, have invented certain new and useful Improvements in Display-Racks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to display-racks de signed for the purpose of displaying, measuring, and cutting oil-cloth, linoleum, or similar materials.

One of the principal objects of the device is to provide simple and convenient means for mounting a series of rolls of oil-cloth, linoleum, or similar materials upon rollers in a rack in a position to unwind and wind any quantity from any of the rolls to measure the same upon a flat surface or table and to cut any desired quantityfrom the roll.

Another object is to provide means for extending the table, or support for the oil-cloth to provide a comparatively long bearingsurface.

Another object is to provide a detachable crank and means for connecting the crank to any one of the rolls of oil-cloth for winding and unwinding the same and dispose it in position to be measured and cut.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a displayrack made in accordance with my invention and showing in dotted lines the table or support extended. Fig. 2 is a front elevation of the same. Fig. 3 is a horizontal section on the line 8 3 in Fig. 1 looking downward. Fig. 4 is a side elevation of the cutting device. Fig. 5 is a vertical section of the same. Fig. 6 is a plan view of the arm which carries the cutter. Fig. 7 is a longitudinal section of the detachable crank-tube. Fig. 8 is a transverse section of the same, and Fig. 9 is a detail view of the rod and spring for holding the cutter in place.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates the upright bars of the rack, there being four such uprights secured together at their upper ends by a cross-bar 2. Said bars converge at their upper ends and at their lower diverging ends being mounted upon casters 3 in order that the rack may be moved about from place to place.

In the outer edges of the uprights 1 a series of inclined notches 4 are formed for forming bearings for the end pintles 5 of the rolls of oil-cloth, linoleum, or similar material. The uprights 1 and cross-bar 2 are suitably braced, as at 6, at the upper end, and at the lower end a cross-brace 7 and a center brace 8 are utilized to give suflicient strength for the'frame below. A sliding table is provided to move between the uprights 1, said table consisting of front legs 9, mounted upon casters 10. The table is supported upon rollers 11, journaled at their ends in the upright bars 1. The top of the table 12 at its rear end is provided with a section 13, hinged at 14 to provide means for giving greater length to the table from front to rear, said table moving upon the rollers 11 and upon a crossbar 15, secured at the upper end of the vertical bar 8 at opposite sides of the frame.

Pivoted to the front legs 9 of the table is a rack 16 to hold the oil-cloth after it has been measured and out. On top of the table extending from front to rear is a scale 17 for measuring the material from the rolls as it is withdrawn therefrom, and extending transversely near the front edge of the table is a rib or bead 18, forming a cutting-surface for the cutter 19. This cutter consists of a holder comprising two blocks 20 21, secured together by bolts 22 and provided with an intermediate recess or slot 23 for the knife or cutter 24. A set-screw 25 is provided for adjusting the inclination of the knife relatively to the holder, and a handle 26 extends upward from the cutterholder 19. The cutter slides between the blocks 20 21, the latter forming a guide.

The cutter-holder 19 is mounted upon a lever'27, provided with lugs 28 and attached by means of screws 29 30, said lever 27 being pivotally mounted upon a rod 31, extending across in front of the table and mounted in brackets 32, secured at the side edges of the table by screws 33. A stop-pin 34 is provided to limit the downward movement of the lever 27, and at the front end of said lever a toe or projection 35 is provided, which bears against the stop 34 when the lever is thrown outward to carry the knife away from the cutting-bead. To hold the lever 27 and the knife-holder 19 in position IIO to cut the oil-cloth, a spring 36 is coiled upon the rod 31, and the ends of said spring are secured to the front edge of the table by means of loops 37 and screws 38, the center of the spring being formed into a loop 39, engaged by a pin 40, secured to the rod 31. By means of this construction the lev er 27 is normally held down to hold the cutter to an operative position, and when the lever 27 is swung outward it is against the tension of the spring 36, owing to the fact that the lever 27 is mounted upon the squared end of the rod 31.

The c ank-shaft for holding the roll. of oilcloth or linoleum consists of a tubular shaft 41, provided with beveled openings 42 at points near its opposite ends, the edges of said openings 42 serving as cams to project and retract fingers 43, pivoted at 44 upon a nut 45, mounted upon the opposite ends of a traveler 46, adapted to be moved in and out of the hollow shaft 41 by means of a yoke 47, secured at one end to the follower, and the opposite end being screw-threaded for the engagement of a rod 48, mounted to rotate in a guide-bracket 49, secured by rivets 50 at one end of the tubular shaft 41. A crank 51 is mounted upon the squared end 52 of a -socket-piece 53, fitted to the end of the shaft 28.

The notches 4 in the uprights 1 below the table 12 can be used for holding rolls of material in position to be moved to the upper notches when it is desired to cut the same.

The operation of my invention may be described as follows: The oil-cloth to be meas- .ured and cut is brought down upon the table 12, the outer end of the same being led over the cutting-bead 18, and when the quantity to be cut has been measured off the cutter 19 is pushed across to sever the material.

The table may be extended outward, if found desirable, during the time the material is being measured, and it can be pushed back out of the way when not in use.

ati on of the crank-shaft will be readily under The op erstood from the foregoing. The fingers 43 are thrown outward to engage the inner layer of the oil-cloth to prevent the same from measure and cut the required length of oilcloth or linoleum from any one of the rolls mounted in the uprights 1.

Various changes in the form, proportion,

provided at the opposite end with a hinged,

downwardly-foldable leaf, said uprights of the rack having devices to support the table and to also support said leaf when the table is drawn out, said devices clearing said leaf when the table is pushed in and permitting said leaf to drop.

2. In a device of the character described, an upright rack for supporting rolls of oilcloth or similar material, a table, a knife or cutter mounted in the holder, a lever to which said holder is secured, a rod upon which said lever is pivoted to slide transversely of the device, and a spring for holding the lever in its normal operative position, substantially as described.

3. In a device of the character described, a cutter secured to a lever mounted to slide upon a rod, a spring for holding said lever in operative position, a toe upon said lever, a stop therefor, and a cutting-bead projecting upward from the table, substantially as described.

4. In a device of the character described, a hollow crankshaft provided with camshaped openings, a traveler mounted within the shaft and provided with pivoted fingers, a threaded shaft, a yoke and a crank adapted to move the traveler to extend or retract the fingers for holding the roll, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
